Nitroglycerin is used as an explosive and as a medication for heart patients. It is composed of 15.87% carbon, 2.22% hydrogen, 18.50% nitrogen, and 63.41% oxygen. What is the
empirical formula of nitroglycerin?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
